Abstract Opera House of Seoul Arts Center was opened in 1993, and is currently Korean representative opera house in connection with size and architectural shape resembling “Katmuri (one of radical components of Chinese characters)”. However, due to fire during performance in December, 2007, remodelling was conducted, and so, finishing materials and interior factors including auditorium, wall and proscenium arch were changed, and acoustic performance was improved. In precedent studies, physical acoustic performance of opera house was assessed through acoustic simulation, and optimal improvement scheme was suggested, and acoustic performance was assessed through actual measurement on the spot after completion of remodelling. However, good results of physical acoustic performance don't necessarily mean good performance of acoustic performance felt by audience. Therefore, physical and subjective acoustic performance should be simultaneously assessed to assess acoustic performance of performance hall. From this viewpoint, this paper aims to assess subjective acoustic performance by conducting auralization experiment through which virtual acoustic field may be experienced at the stage of design after conducting optimal acoustic design through computer simulation on. After that, through the actual measurement after the Opera House of Seoul Arts Center was completed, the thesis investigated the characteristics of room acoustic and examined the reliability if it was constructed suitably for acoustic simulation. Also, the paper figured out the ordinary people's satisfaction of acoustic efficiency through psycho-acoustic experiment in the actual site.
